1 has wheels 21, 21 at one end thereof and leg This invention relates to new and useful improvements'in elevators adapted to carry'various materials such as bales of hay and other farm produce from a low level to a higher one such as to a barn loft.

The principal object of the present invention.

is to provide an elevator of the character stated which can be very conveniently moved about and adjusted to the desired height.

Another important object of the invention is to provide an elevator of the character stated which can be manipulated by a single person with ease and-efllciency. Y

- Other objects and advantages of the invention will become apparent to the reader of the fol lowing description.

In the drawings- Figure 1 represents a side elevational view of the elevator.

Figure 2 is a top plan view.

.members 23, 23 at its opposite end. As shown in- Figure 1, the legs 23 extend upwardly above the truck 23 and the conveyor 5 is fulcrumed thereon as at 23. I

The means for adjusting the inclination of the conveyor 6 comprises a pair of depending rack bars 3|, 3| each hingedly secured at its upper end as at 32 to the corresponding side wall 3. The adjusting means further comprises a pair of upstanding rack bars 33, 33 each hingedly secured as at 34 to the frame 35 of the truckiii.

Each rack bar 33 in conjunction with its companion depending rack bar 3] has a guide sleeve through these sleeves a shaft 36 is disposed and Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1.

Figure 4 is a fragmentary vertical sectional view taken substantially on the line 4-4 of Figure 2.

Figure 5 is a fragmentary side elevational view of the adjusting means.

Figure 6 is a sectional view taken substantially on the line 63 of Figure 5.

Referring to the drawings wherein like numerhas a hand crank 31 at one end thereof. Numeral 38 denotes a slide block notched at its lower end for receiving the shaft 36, this shaft being square as shown by portion 33 in Figure 6, the block securing the shaft against rotation when the block is engaged therewith. The slide block 38 has an opening 38b therein and this opening receives an elliptical end portion 380. of shaft 33, which when rotated by handle or the like will serve to elevate the block so as to disengage the same from a notched wheel on the shaft 36 and permit free rotation of the shaft 38.

Inside of the sleeve is a gear 40 which meshes simultaneously with the opposed teeth of the rack als designate like parts, it can be seen that the. elevator comprises an elongated conveyor generally referred to by numeral 3. This conveyor comprises a pair of side walls 3, 3 between which is a floor I along which ride the top flights of a pair of conveyor chains 3, 3 connected by bale between the side walls 6, {serve to assist in supporting the floor l.

Transversely extending shafts ii, l2 are at which is a pinion l3 meshing with the gear-wheel II on one end of the shaft II. There is another gear l3 on the other end oi the shaft i2 meshin: with a second pinion l3 onthe shaft l3.

.Theshaft llhas apulley wheel 20 at one end thereof over which a belt II from a small pulley 33 is trained, this pulley 23 being driven by an electric motor 23 situated on a platform 34 carnedbytheframezlofatruckzawhichtruck 35 ated simultaneously for raising or lowering the or other material moving slats 3. Cross bars ill bars 3|, 33. The shaft 36 extends through both of the sleeves 35 and the gears 43 are located on the same shaft. Obviously, by tuming'the hand crank 31, both sets of adjusting devices are actuconveyor 3.

A draft bar 4| is slidably disposed through cross members 42, 43 forming part of the frame 33 and can be pushed to the out of the way 40 place shown in Figure 3 when not in use. the upper and lower ends of the conveyor 3, the upper shaft Ii having sprocket wheels l3, l3

when the tonguebar 4| is to be used, the same can be pulled out so that its eye end 44 will be exposed and in thisposition a cross pin 45 disposed through the opposite end of the bar will abut the cross member 43.
